STOP AND WASTE COCK.

SPECIFICATION forming part of Letters Patent No. 770,173, datedSeptember 13, 1904.

Application filed January 9 1904.

To all whom it may concern;

Be it known that 1, PETER HEALEY, a citizen of the United States,residing in Evansville, in the county of Vanderburg and State ofIndiana, have invented certain new and useful Improvements in Stop andWaste Cocks, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, formingpart of this specification.

My invention relates to a stop and waste cock so constructed as to beoperated by either right or left hand movement of the plug-valve in thecock, thereby avoiding the necessity of making separate cooks for rightand left hand use.

Theinvention consists in features of novelty hereinafter fullydescribed, and pointed out in the claim.

Figure I is a plan view of my stop and waste cock with the handlethereof omitted. Fig. II is an elevation of the cock with the handleshown in place therein. Fig. III is a face View of the neck of the cockand the head of the plug-valve seated in said neck. Fig. IV is across-section taken on line IV IV, Fig. II. Fig. V is a cross-section ofthe cap by which movement of the plug-valve is governed. Fig. V1 is anenlarged perspective view of the neck of the cock and head of theplug-valve passing therethrough, the plug-valve-controlling cap beingshown in cross-section.

1 designates the housing of my stop and waste cock, which is designed tohave its ends united to sections of pipe leading thereto, as seen inFigs. I and II. Projecting from the front of the housing 1 is the usualdrain-nipple Q. Mounted in the housing 1 isa plug-valve having in itsbody the ports common to draincock plug-valves.

3 designates the neck of the cock-housing 1, from which extend a pair ofbosses 4, located diametrically opposite each other.

5 designates the head of the plug-valve, which projects through the neck3 and the main body of which extends beyond the bosses 4, terminating ina shoulder-seat 6.

7 is the outer circular end of the plug-valve head that extends beyondthe shoulder-seat 6 am No. 188,415. (No model.)

and contains a socket 8, by which a handle 9 is received.

1O designates a cap having an inwardly-extending rim 11, that rests uponthe shoulderseat 6 of the plug-valve head and within which is anaperture 12, that receives the outer end 7 of the valve-head. The cap 10also has a flange 13, that extends inwardly from the rim 11 and isfittedto the bosses 4, carried by the cock-housing neck, as seen in Figs. II,IV, and VI. On the interior of the flange 13 is a single boss 14.

15 is a set-screw that passes through the cap-flange 13 and boss 14interior thereof, as seen most clearly in Figs. IV and V. This set-screwis adapted for insertion through a screw-threaded hole 5, extendingthrough the main body of the plug-valve head 5 to the socket 8-, thatreceives the handle 9.

When the cap 10 is applied to the head of the plug-valve of my stop andwaste cock, its rim 11 rests upon the shoulder-seat 6 of the plug-valvehead-body, as seen most clearly in Fig. VI, and the outer end of the capis thereby held away from the bosses 4 of the cockneck, so as to rideentirely with the head of the plug-valve without any bearing against theends of the bosses 4. After the cap has been seated, as stated, theset-screw 15 is inserted through the flange 13 and boss 14 of the cap isintroduced through the hole 5f in the plug-valve head and the cap isthereby firmly united to the plug-valve with the boss 14 of the capoccupying a position between the neck-carried bosses 4, thereby limitingthe movement of the plug-valve to a degree permitted by the spaceexisting between opposing faces of the bosses 4. The movementfor theplug-valve thereby provided is rendered either right or left handaccording to the position of the cap-boss 14. Where it is desired toprovide opposite movement of the plugvalve, the cap 10 is removed fromthe valve and turned to position its boss 14 between opposing faces ofthe bosses 4 opposite that in which it was previously located, and thevalve is rotated to bring the hole 5 in the valve to the side occupiedby the cap-boss, and by then inserting the set-screw into the hole 5 thedesired reverse movement of the plug-valve is secured. The set-screw 15,by extending through the plug-valve head into the socket 8 therein,serves to hold the handle 9 in place in said socket by engaging theinner end of the handle, as seen in Fig. IV. I claim as my invention. yIn a stop and Waste cock, the combination of a housing-neck, a pair ofbosses projecting from said neck, a plug-valve having a head providedwith a threaded hole, a shoulder-seat on said valve-head located beyondthe ends of said neck-carried bosses, a circular end projecting fromsaid valve -head beyond said shoulder-seat,-a cap having a centralorifice fitted to said circular valve-head end, a rimforming a part ofsaid ,cap resting on said shoulder-seat and thus keeping the cap fromfrictional engagement With the end face of said neck-carried bosses, astraight flange extending from said rim to a point below the lowerterminus of said neck-carried bosses, a boss on the interior of saidflange intermediate of said neck-carried bosses, said flange and bosshaving a threaded hole registering with the threaded hole in theplug-head, and a set-screw passing through said threaded holes,substantially as set forth.
